Former Philadelphia 76er Charles Barkley called his former team "a joke" for not having a coach this late in the NBA offseason.

According to CSN Philly, Barkley voiced his opinion about the Sixers not having named a head coach this late in the offseason. He wasn't particularly pleased.

"I think that's one of the silliest things that I've seen in sports for a long time. I'm in Philly during the summer as you know, and I'm watching and reading every day - to not have a coach under contract by now, I think that's a joke. I don't know what they're waiting on. You're playing summer-league games, people need to know who's in charge. They got players who are playing in the summer league, they got assistant coaches coaching the team. You just can't bring somebody in, and him have instant credibility - he has to build rapport with the players."

A separate CSN Philly report confirms the two candidates who are being considered for the vacant head coaching position are current Sixers assistant Michael Curry and San Antonio Spurs assistant Brett Brown, citing a tweet from ESPN's Marc Stein.

2013 marks Curry's third year with the Sixers. He joined former head coachDoug Collins' staff in 2010 and called the shots for the team during this year's summer league play in Orlando. He was the Detroit Pistons' head coach in 2008-09 but was dismissed after a 39-43 finish and a first-round playoff exit.

On the other hand, Brown is in his seventh year as one of Gregg Popovich's assistants. Prior to this, he was a player development coach with the Spurs for five years. He was the coach of the Australian men's basketball team in the 2010 summer Olympics in London.

The Sixers' head coaching position was vacated after Collin's resignation on April 18. He was Philadelphia's coach for the past three seasons.

Barkley played for the 76ers from 1984-1992. He retired in 2000 while securing his place in NBAhistory as the fourth player to score 20,000 points, grab 10,000 rebounds and register 4,000 assists. He was named as one of the NBA's 50 Greatest Players in 1996 and was inducted into the professional basketball Hall of Fame a decade later.
